[NEW CONTENT] Document class-based tools approach

[zastrowm]

Proposed Content

Callouts on how to create class-based tools which enable customizing the behavior of the tool + dynamically changing properties.

Location

https://strandsagents.com/latest/user-guide/concepts/tools/python-tools/

Rationale

A proposed use case:

I'd like to have a file_read tool and want to dynamically change various restrictions like file extensions, directories, basically to pass in variables that the LLM can't mess with

Using modules or @tool decorator, the tool is basically a singleton

Users can already:

• Derive from PythonAgentTool (not preferred) or create a class in which @tool methods are exposed as tools (preferred), but we don't document this anywhere.
